K1-V116 Wine Yeast Lalvin - Saccharomyces cerevisiae
Highly recommended for dry whites, aged reds, and late harvest wines.
Lalvin K1™ (V1116) has been selected by INRA Montpellier located in France in the Mediterranean region. When fermented at low temperatures (below 16°C) and with the right addition of nutrients, Lalvin K1™ (V1116) is one of the yeast producing the most floral esters (isoamyl acetate, hexyl acetate, phenyl ethyl acetate). These esters bring fresh floral aromas to neutral varieties or high-yield grapes. Among the high ester producers, Lalvin K1™ (V1116) is the most resistant strain in difficult fermentation conditions, such as low turbidity, low temperature and low fatty acid content. Lalvin K1™ (V1116) is also a proven strain for the fermentation of ice wines.
Selected by the Institute cooperative du vin in Montpellier among numerous killer strains isolated and studied by Pierre Barre at INRA, the K1V-1116 strain was the first competitive factor yeast to go into commercial production and has become one of the most widely used active dried wine yeasts in the world.
Oenological properties and applications
The K1V-1116 strain is a rapid starter with a constant and complete fermentation between 10° and 35°C (50° and 95°F), capable of surviving a number of difficult conditions, such as low nutrient musts and high levels of sulphur dioxide (SO2) or sugar. Wines fermented with the K1V-1116 have very low volatile acidity, hydrogen sulphide (H2S) and foam production.
The K1V-1116 strain tends to express the freshness of white grape varieties such as Sauvignon Blanc, Chenin Blanc and Seyval. The natural fresh fruit aromas are retained longer than with other standard yeast strains. Fruit wines and wines made from concentrates poor in nutrient balance benefit from the capacity of K1V-1116 to adapt to difficult fermentation conditions. Restarts stuck fermentations.
